_______________ contains solid particles that are sufficiently large for sedimentation.

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. Pure substance

  2. Element

  3. Suspension

  4. Solution

Show answer
Correct Option: C
Explanation:

A suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer.

If a liquid is suspended in another liquid, it is called :

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. emulsion

  2. aerosol

  3. colloid

  4. particulate

Show answer
Correct Option: A
Explanation:

Putting two or more liquids together creates an emulsion if the liquids do not mix. If a liquid is suspended in another liquid, it is called an emulsion.

A suspension of liquid droplets or fine solid particles in a gas is called :

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. aerosol

  2. particulate

  3. both a and b

  4. colloid

Show answer
Correct Option: C
Explanation:

A suspension of liquid droplets or fine solid particles in a gas is called an aerosol or particulate. In the atmosphere these consist of fine dust and soot particles, sea salt, biogenic and volcanogenic sulfates, nitrates, and cloud droplets.

Which of the following is an example of suspension?

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. Milk

  2. Water

  3. Sand in water

  4. All of the above

Show answer
Correct Option: C
Explanation:

A key characteristic of a suspension is that the solid particles will settle and separate over time if left alone. An example of a suspension is a mixture of water and sand. When mixed up, the sand will disperse throughout the water. If left alone, the sand will settle to the bottom.

Paste is:

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. suspension of solid in a liquid

  2. mechanical dispersion of a solid in liquid

  3. colloidal solution of a solid in solid

  4. none of the above

Show answer
Correct Option: A
Explanation:

Paste is suspension of solid in liquid.

Suspension is a : 

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. compound

  2. mixture of two or more substances

  3. have only single type of particle

  4. none of above

Show answer
Correct Option: B
Explanation:

Suspension is the heterogeneous mixture of two or more substances. In suspension, particles are suspended throughout in bulk and can be seen by naked eyes.

Which of the following has liquid as a dispersing medium?

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. Aerosol

  2. Gel

  3. Foam

  4. Cranberry glass

Show answer
Correct Option: C
Explanation:

Mixtures are called foam when liquid is present as dispersing medium and gas is dispersed medium. For example, shaving cream, soap bubbles, etc.

A suspension of liquid droplets or fine solid particles in a gas is called as :

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. aerosol

  2. foam

  3. emulsion

  4. gel

Show answer
Correct Option: A
Explanation:

A suspension of liquid droplets or fine solid particles in a gas is called an aerosol or particulate. Aerosol is of two types: liquid aerosol and solid aerosol.

Smog is an example of:

chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. ice dispersed in air

  2. water dispersed in air

  3. smoke dispersed in air

  4. smoke and water dispersed in air

Show answer
Correct Option: D
Explanation:

Smog is a colloidal solution in which the dispersed phase is solid and dispersion medium is gas along with some water droplets dispersed into the air.

Match the List-I (Colloidal dispersion) with List-II (Nature of the dispersion) and select the correct answer using the codes given below the lists:

Lits-I(Cooloidal dispersion) List-II(Nature of dispersion)
A. Milk 1. Solid in liquid
B.Clouds 2. Liquid in gas
C. Paints 3. Solid in solid
D. Jellies 4. Liquid in liquid
5. Liquid in solid
chemistry nature of matter heterogeneous mixture - suspension and its properties suspension types of mixture

  1. A- 4; B- 2; C- 1; D- 5

  2. A- 1; B- 5; C- 3; D- 2

  3. A- 4; B- 5; C- 1; D- 2

  4. A- 1; B- 2; C- 3; D- 5

Show answer
Correct Option: A
Explanation:

Milk is an emulsion of dispersed phase as a liquid in the dispersion medium as a liquid. This makes A-4, excludes Option B and D from answer choice.
Cloud is aerosol where dispersed phase is liquid and the dispersion medium is gas, Thus this makes B-2.
Paint is a solid phase in liquid medium makes C-1 and Jellies are a liquid phase in solid medium makes D-5.
Thus, option A is correct.
